9 Claims. (Cl. 285-27) This invention relates to a hose coupling connection and has for an object the provision of a hose-to-nipple connection, as for a coupling, which will provide a very secure attachment for the hose; which will not cut or damage the hose; which can be very quickly and easily ;means for dividing the action between a plurality of axially spaced gripping rings. The invention also includes improved means for locking the parts of the connection together.
The objects of the invention as well as various features of novelty and advantages will be apparent from the following description of an exemplary embodiment of the invention, reference being made to the accompanying drawings, wherein:
FIG. 1 is a side elevation and section of a coupling connection embodying theinvention, a hose being shown in final connected position;
. FIG. 2 is a similar section made; I
FIG. 3.118 asection like the upper part of FIG. 1 but showing .a pre-finaI position of parts with a locking ring being, inserted; 7
FIG. 4 isa side elevation of a locking ring;
FIG.-5 is an elevation of a portion of one of the rolling' gripper rings shown in FIG. 1.
V I As shown in the drawings, a hose is connected to a nipple 11 -vvhich is provided with some means, threads 12 being shown, for securing it insome assembly; The usual assembly isa hose coupling with-a similar mating hose connection and means for securing the coupling parts together; but the invention is fully disclosed by showing one partof the coupling, so it is not necessary to show the other one or the means-for securing them together.
, The nipple is provided with an annular external rib 13 having a radial surface 14 which is adapted to be engagedby ,the end of the hose. The nipple is also provided with a shallow and rather long annular recess 15 on the outer side near the end into which the hose material can be squeezed for sealing without damage to the inner linbefore the connection is ,ing when connected. The end of the nipple is rounded, .as indicated at 16, to avoid cutting the hose.
to by the numeral 21 will be designated as the secondary gripper or sealing grip ring.
"Each annulus or grip ring 20, or 211, is stretchable and compressible circumferentially so as to assume various lannulusgdi'ameters, in the present case this character being imparted by an annular spring wire coil 22 which is connected together at its ends. On this spring Wire annulus there are threaded a plurality of generally cylindrical rollers 23 of any suitably rigid material, one example being aluminum, with alternating disks 24 of elastomeric material, such as rubber, neoprene, or the like.
A sleeve or collar 27 has the annulus or annuli grip rings 20, 21 inserted and the collar is pushed on the hose before the hose is pushed on the nipple. The sleeve 27 is provided with an annular tapered or frusto-conical surface 28 which functions to wedge the annular grip rings 20, 21 down on the hose with a rolling action. An annular radial surface 29 on an inwardly extending rib on the sleeve limits the movement of the grip ring within the sleeve in one directionand assures that it is located in a proper initial position.
. An annular index and hose enclosing band 30 is provided on a seat 31 on the rib 13 of the nipple, and is secured thereon, for example, as by being punch-staked at various points around its circumference. Holes 32 are provided in the sleeve around its circumference for drainage.
There is sufficient space between the inner surfaces of the sleeve 27 and the hose 10 for the band 30 to enter the sleeve when the parts are secured together.
There is enough space inside the end surface 33 for a snap lock ring 34 to be inserted, the surface 33 being tapered for easy insertion of the ring after the parts have been assembled. Initially this lock ring, which is .springy, is spread apart axially at its ends. The ring 34 fits in a groove 35 in the sleeve and can enter this groove when the sleeve is fully pulled up on the nipple, asshown in FIG. 3. One edge of the ring will engage an annular radial surface 36 on the rib 13 if the parts later begin to move apart axially. An annular shoulder at the inner edge of the radial surface 36 prevents the ring from moving back radially inwardly after being installed. Annular radial surfaces 37 and 38 on the nipple 27 and sleeve 10 respectively interengage (FIG. 3) when the parts are fully drawn together to stop further movement. In the final position with the locking ring seated (FIG. 1)-the surfaces 37 and 38 are spaced slightly apart.
In making the assembly the parts are pre-assembled as described, then the sleeve is pulled up onthe nipple and hose. For large sizes a Wheel-puller type tool can be used. .Since the roller bands are tight on thehose they will remain in position until the tapered surface 28 of the sleeve engages them and rolls them down in wedging position on the hose. Due to the selected difference in annulus section diameters the bands will be spaced apart axially in final position. 7
Due to the rigid tapered backing surface of the sleeve the roller bands will at all times penetrate evenly into the hose around its circumference. When the connectionhas been made, any pull on the hose will make the roller bands penetrate more deeply and hold more securely.
The roller grip rings penetrate the hose evenly and prevent cutting through the hose liner tube and creating a potential leak. The annular groove 15 is cut'in the nipple .or a' tapered nipple may be used, in either case the purpose being toielieve the "radially inward'pressure on the nose at 'the'secondarygrip'ring. This creates ajsituati'on where the primary grip ring acts to hold the hose and thesecondary gripring acts mainly for sealing. jTheouter end 40 of the sleeve is spaced away from the hose and rounded so that no breakage-starting cutrin the hose can begin here.
The relative form and efficiency and permanency of the coupling. The surface 29 against which the larger ring engages is spaced the cor-l. rect distance 7 from ,:the end of; the sleeve, which is positi'on'ed at the end of the gage band 30, toassurethat when position of parts, both in initial a position and in final position,- have great importance in the the parts are fully drawn up," as shown in FIG. 1,.-the
smaller ring will be disposed above thexsrnaller-diameter portion or groove 15 of the nipple toperform'the sealing larger ring will be positioned above the larger diameter portion of the nipplev to perform. its gripping actionat a point nearer the endof the hose. than'the point engaged I action without undulyjcuttingjintothe hose'and' that the in which said nipple has an annular rib beyond the end of the hose, iiiii/liih said sieevegnas an. interior annrnar groove disposed axially inwardly beyond the nipple rib in final assembly, and in which said means for holding the nipple and sleeve together' compris'es'a split locking ring which is'resilient circumferentially and axially and which in its free position has its ends spaced apart circumferem an annular sleeve embracing said nipple, hose and gripby the .smaller'rin'g. The'annulus diametersrof the rings are so proportioned that" the larger'ring .will be engaged first by the tapered surface of the sleeve and rolledaway from the smaller ring as the parts are tightened so asnto leave the rings spaced apartin final assembly, as shown-in FIG. 1. At'no time during the drawing together of the parts is either :ring engaged by a radial surface which.
would hinder the free rolling action of the cylindrical segments of the rings, By-havingfcylindri'cal segments the}.

It is thus seen that the invention providesja simple, effective and convenient hose coupling connection which can be easily installed or' removed.

hose is increased yet with minimum tendency to damage 7 the hose. While one embodiment of the invention has been described 'for' purposes of illustration, it is 'tobe understood that there may be various embodiments 'and modifications within theogeneral scope of the invention,
